To all whom it may concern."

Be it knownthat I, EDWIN ALBERT BAKER,-

a citizen of the United States, residing at of New York, State of New York, have invented certain new and useful Improvements in Detachable Rims for Vehicle-Wheel' Tires, of which the following` is a full, clear, and exact description.

ly invention relates to improvements in vehicle wheel tires and particularly of the detachable rim typefor motor vehicles and the like where it 1s often desirable to change tires quickly.`l` y c The ordinary:l ty e of pneumatic tire` is provided with' a va ved inlet stem and also provided with lugs-for securing theA tire to .the rim.

It is my main object toseeurethe tire to the wheel so that the valve stem and' lugs are not interfered with. This makes it possible to utilize'ordinary commercial tires'without alteration. f

Another object is to facilitate the attachment and detachment of the tire and rim to the wheel.

Another object is to prevent' binding.

Another object is to take up wear-and inequalities in dimensions.

Another object is to adapt the tire to racing as well as road use.

The principles 'of the invention are illustrated in the accompanyingtwo sheets of drawings. j

Figure `1 is a side view of a vehicle `wheel with the improvements of my invention. Fig. 2 is an edge view and partial transverse sectional View of the same. 'Fig. 3 is an enlarged fragmentary side elevation, parts being omitted. Fig 4 is a full sized fragmentarir sectional view showing the invenition. Fig. 5 is a fra ymentary vertical-section showlng details o construction. Fig. 6

the attaching mechanism. Fic. 7 is a perspective view oi a fragment oi the tirerim and part of the attaclnng mechanism. Fig. 8 is a plan view of two take-up blocks for assisting in securinfrthe parts together.

The wheel is ofb the ordinary construction, for instance, having spokes such as 1, and hub 2, and a rim 3.

l The tire 'isof the ordinary construction, for instance, having a shoe 4, with tongues 5, 5 locked to the tire rim 6, beneath the beads?,

7 by means of ordinarylugs such. as 8. The

stem 10. Between the rims of the wheel and the tire,

I locate what ma lbe termed a spaer'll,

formed of channe iron whichisfsec'ured to the rim 3, at a number of points, such as 12 l andhas a number of intermediate r platforms, such as 13, spaced apartfrom rim. 3. The tire rim 6,'is secured Vto platforms 13, 13 as hereinafter described, the` for fastening the tire to' its rim and the the raised va ve stem being located4 between the raised platforms so that there lis 'no'interferenc with them.

On each platform 13;' is securelyfasteiied' "a plate 14, preferably formedif bronzeer similar noncorrodible metal and having an j L shaped recess 15, withan entrance'on one side.

A plurality of blocks'such c3116, are secured to a tire rim 6, andcorrespondin number and position with the recesses 15, so

that the tire rim may be placed in the posi` tion with its blocks opposite the inlets to the recesses. The tire rim may then be pushed into place so that each block 16, willtake'up a position as indicated by the dotted lines in the righthand ends of the'recesses 15, in F' .s I

6. 'Io secure the tire rim and blocks .1 6, m'

position, I provide a pair of take-u memers such as 17, and 1.8, (see Fi 8 which side t rou h the may be inserted from the bum j mouth or inlet in recesses 15. The t screw 19, fits into a tapped opening 29, inthe platform'12, and is wedge-shaped take-u block 1'8, against-the inclined surfaces of th ytakeup block 1 7, and the plate 14, so as to securely hold the parts in position and take up all looseplay. The action of this wedge member m'oves the block 17 toward theright, but also forces it outagainst the tire rim 6, so that a double function is performed which effectively 'secures the'parts. The thumb.- nut 21, operating ,on the shank of thumb-y screw 19, presses againsta washer 2 2, and

serves to prevent the thumbscrew 19, -fronif An elongated slot 23, per--v purpose of working loose. mits access to block 1 7, -for the prying it out in case of jamming, and pivoted spring 24,- may be em loyed to assist in holding the takelup mem ers 17 ,"and 18, in position.

The construction thus far described vis suitadapted Ato force "the- L...

4able for the Wheels of racing vehicles `iivhere light Weight and ready accessibility is essen- For ordinary commercial and road veh icles it may in some cases .be desirable to inclose the spacing member and the, lugsand valve stem.' This is accomplished by means of two annular rings 25, and 26V.- -The first may be' pjelrmanently or otherwise secured in ethe second, which covers the en- W trance to the recesses 15, is removable. For this urpose it is provided with a number of keyoleslots such as 27, and clan1pnuts such as 28, re provided tocoperate therewithso t at the ring 26, may be attached and detached readily.

The advantages of my invention will be appreciated by 'those acquainted with the art,y and particularlyI when the herein above- -mentioned objects are considered.'

5. In a wheel construction, a` Wheel rim having a plurality of raised platforms and a recess in each platform, a tire rim with tirey and inwardly extendlng lugs and valve stem accommodated in the spaces between said platforms, blocks carried by the tire rim and fitting said platform recesses, and radially adjustable means carried by said platforms for forcing lsaid blocks vcircumferentiallyl and holding them in place, one of said parts being provided with an inclined surface.
